[blktests,v3,3/3] nvme/{041,042,043,044,045,048}: Use default hostnqn and hostid

Commit Message

Daniel Wagner July 3, 2023, 9:16 a.m. UTC

The host might have enabled the udev/systemd auto connect feature.
This disturbs the blktests for the fc transport. nvme-cli is able
to distinguish between the different invocations via the --context
option.

Instead creating random generated IDs or reuse the hostnqn, it's safer
to always use the same hostnqn to reduce the risk that the matching
logic doesn't work.
